Does daylight saving change NPT to JST?
Nepal Time does not move its clocks at all, so its UTC+5:45 offset holds every day of the year.
Japan Standard Time does not move its clocks at all, so its UTC+9 offset holds every day of the year.
Is NPT ahead of or behind JST?
NPT is behind JST by 3 hours 15 minutes: when it is 12:00 pm in Nepal, it is 3:15 pm in Japan. Neither Nepal Time nor Japan Standard Time observes daylight saving, so the abbreviations never change and the gap between them is fixed.
Nepal Time covers the only national zone on a 45 minute offset. Japan Standard Time covers Tokyo, Osaka and the whole of Japan. The identifiers behind them are Asia/Kathmandu and Asia/Tokyo, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
